People who are hospitalized, including the elderly, are often immunocompromised and susceptible to infection of all kinds, including MRSA; an infection by MRSA is called healthcare-associated or hospital-acquired methicillin-resistant S. aureus (HA-MRSA). [1] [5] [22] [23] Generally, those infected by MRSA stay infected for just under 10 days ...
Now, methicillin-resistant Staphylococcus aureus (MRSA) is not only a human pathogen causing a variety of infections, such as skin and soft tissue infection (SSTI), pneumonia, and sepsis, but it also can cause disease in animals, known as livestock-associated MRSA (LA-MRSA).
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
PBP2a is known to give staphylococci resistance to other β-lactam drugs and PBPx does the same for pneumococci. Ceftobiprole also has an aminothiazoyl-hydroxyimino side chain at the C-7 position which is known to give good resistance to β-lactamase from S. aureus. Together these active groups make ceftobiprole bactericidal to MRSA.
Its role in therapy has been largely replaced by oxacillin (used for clinical antimicrobial susceptibility testing), flucloxacillin and dicloxacillin, but the term methicillin-resistant Staphylococcus aureus (MRSA) continues to be used to describe S. aureus strains resistant to all penicillins. [5]
Staphylococcus bacteria is one of the leading community-acquired bacteria. According to the CDC, [10] after a push from hospitals to better prevent staph infections, the percentage of people affected has dropped dramatically. However, staph infections are still prominent and a cause for concern among healthcare professionals, especially new ...
Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [2] and released to the public in January 2007. [3] Quizlet's primary products include digital flash cards , matching games , practice electronic assessments , and live quizzes.
Over time, most of the strains of bacteria and infections present will be the type resistant to the antimicrobial agent being used to treat them, making this agent now ineffective to defeat most microbes. With the increased use of antimicrobial agents, there is a speeding up of this natural process. [29]
